#JOBO C 41 PRESS KIT SERIES#
I have never had access to a 4107 to verify the same is true, but my working theory is that the 4100 series tanks were modified inversion tanks that served as prototypes with the early Jobo processors, before being replaced with more “finished” designs with the 4300 series tanks. The tank is actually a 2336 inversion tank, with a (uneven) band epoxy-welded around it to rest on the processor’s bearings, a magnet epoxy-welded on top of the tank capacity writing, and a new label stuck on with rotary capacities inscribed on it. The 4106 tank is the standard tank I’ve been using since I got my Jobo CPA. The other major oddity is the 4106/4107 tanks. Needless to say, they are uncommon today. It is (along with the 2400) in fact a daylight tank, designed to be loaded by someone without access to a darkroom, dark tent, changing bag, or wardrobe with a duvet over their head. The 4324 doesn’t follow the increasing size of the previous three models. Additionally, the 5×4 reels can take 6 sheets.įour tanks are oddities here. This allows 2×126 films for each 135 reel, 2×110 films for each 16mm reel, 2×127 or 2×120 films on each of those reels. Note on reels: “Duoset” reels have a red plastic pin, and allow two films to be loaded onto a single reel.
Most reels and inversion tanks are given a “2000” designation, while tanks built or converted for rotary use are given a “4000” designation. They use a different design of magnet, a different diameter and different reels. The System 2000 tanks are not intercompatible with the 2500 series in any way.
Both tank types were usable in all processors (subject to the volume limits of the CPE’s), but parts were not interchangeable. This gives a theoretically more even development for film, and allows processing of sheet film. Like the current 2500/1500, the 2000 was a larger diameter tank. In the early days of Jobo, these were the System 2000 (or “Professional Series”) tanks, and the System 1000 (or “Amateur”) tanks. The Good Old DaysĪlways two there are, a master and an apprentice. This means that 1000, 2000 and other tanks fitted with inversion lids may not be used with the Autolab. These are the 1500, 25 series tanks with cog lid (plus 2800 series paper drums, for those using it for RA4 or very large sheet film). Designed for the ATL series Autolab processors, they will only work in an Autolab, or a CPA2/CPP2/CPP3 with lift.įinally, the Autolab processors are only compatible with those tanks that support the lift accessory. The System 3000 (also called ‘expert’) tanks are used for processing paper and sheet film in large sizes with exceptional consistency. In practice, this is only a significant issue for sheet film photographers, as this generally limits CPE users to the current (and expensive) 2509/2509n 5×4 reels in a 2520 or 2521 tank. The CPE series are compatible with all tanks from the 1000, 1500, 2000, 2500 ranges that require 600ml or less of chemistry. This means that they are unable to handle larger tanks (such as the 4323) because the high drag from the chemicals would strain the motor. The CPE, CPE2 and CPE3 are limited to a 600ml total chemistry because of the weaker motor in these processors. Non-expert tanks with cog lids can generally be used without a lift on any compatible processor, as long as they have a magnet on, and you don’t turn them upside-down.
The CPA and CPP do not support the Lift accessory, and as such are incompatible with the Expert tanks. In theory, the same compatibility should be true of the 4100 processor that preceded the CPA, though having only ever heard of one once, I can’t say for certain. With the exception of the System 3000 – all tanks will work on a CPA, CPP, CPA2, CPP2 or CPP3. It should be noted that not all tanks can be used on all Jobo systems. So lets have a look at the complete collection. Following a slight accident involving the “buy it now” button on eBay, combined with doing some research for a friend, my collection (and understanding) has expanded significantly. The 4106 is a rather more versatile tank that accepts 5×135, 3×120 or 2×5-4 sheet film reels. The 4322 is a small tank, designed for one 120 reel (2×120 or 1×220 rolls) or two 135 reels (that each take one roll). My CPA came with two film-friendly tanks: a 4106 and a 4322. For one, I remembered that I have a blog I never write in – and for another, my Jobo kit has been expanded again. Ah, that sweet time of the year, when it’s too dark to do anything outside and I return to my lab to enjoy the sweet bliss of carcinogenic chemistry fumes and eyestrain.īut something is a little different this year.
